What is the image size or aspect ratio for a background image that will fill the Half Life 2 welcome screen. For some reason my welcome background image is too small (1024x768) and repeats itself in the welcome display image. I measured the space on the screen and its 10 inches by 5 inches but if I make a image that size (10x5) it repeats itself even worse. I am sure this is a really simple thing and is more HTML related than HL2 related.
